'DISHWASHING MACHINE Application filed-October 12, 1927. Serial No.225,767.

The invention relates to dish washing machines, and has for its objectto provide a machine of such type by means of which dishes, cutlery, andother articles may be quickly and effectively cleansed, and in which nohandling of the articles is necessary during. the cleansing operation. Afurther object is toprovide in connection with such a machine `arotating brush onto which `water isdischarged and thrown by the brushwith much 'force against the articles to be cleansed, and means carriedby a receptaclehousing the brush adapted to support the articlesarranged about the brush at avdistance so as to more or less receive thesplash of the water, and whereby the splash of the water directlyhitting the wall of the recepf tacle between the -spacings of thearticles reaches the parts of the articles not direct-ly 2o exposed tothe spray produced by the rotating brush. A. still further object is toprovide a'motor having a shaft which carries the rotatable brush andalso serves as a drive for an impeller or pump which delivers water tolsaid brush.

With the above and other objects in view, the invention resides in thecombination and arrangement of parts as hereinafter set. forth, shown inthe drawing, described and claimed,

3o it being understood that change's in the precise embodiment of theinvention as shown.

may be made within the scope of what is clalmed withoutv departing fromthe spirit of the invention. Y v

In the drawing: v Figure 1 is a view of the dish washing machine showingthe receptacle thereof in vertical section, and all other parts .inelevation.

Figure 2 is a top view of the washer 'with `the receptacle coverremoved.

'Referring to the drawing,rthe'numeral 1 designates a receptacle,preferably cylindrical in form, provided with a cover 2, and having aninwardly slopingrr bottom 3 terminating centrally of the receptacle in awell4 into which the water used in vthe washing operation drains forrecirculation. The well 4 i provided with an outlet-14, which may be 50closed by the use of an ordinary plug (not shown), or to which a hosemay be attached for conveying water from the well to a floor drain orelsewhere, as may be desired.

The receptacle 1 is supported by a plurality of leg members 5, to whichare secured arms 6 for supporting an electric motor 7 disposed beneaththe well 4, and the shaft 8 of which extends vertically through saidwell. Disposed within the well 4 is a pump or impeller 9, from thecasing of which extends a vertically disposed pipe 10, which pipe isreturn bent at its upper end so that Water will be discharged therefromdownwardly onto the upper end of a vertically disposed brush 11 which ismounted on the end of the motor shaft 8. Said motor shaft' 8 alsoextends through the impeller casing and on which the .impeller bladesare mounted, said casing being provi ed with an intake opening 15.Carried by and isposed about the inner sides of the receptacle and atvarious heights therein are a series of inwardly and downwardly inclinedfingers 12, and provided with hooked ends Yand relatively spaced forholding the articles to be washed, such as lates, cups, saucers andother table ware. isposed adjacent the Aupper end of the receptacle isaseries of closely spaced fingers 13 suitable for receiving therebetweenand supporting knives, forks, spoons, etc. l

In operation, hot soapy water suiiicient to fill the well 4 is pouredinto the receptacle, and the .dish'es and cutlery positioned on thefingers 12 and 1-3, and so arranged that the' same will be mosteffectively exposed to the spraying action of the water thrown outwardlyby the rapidly rotating brush driven by the motor, and to which thewater is conducted by the impeller and pipe leading .therefrom to apoint above the brush. The water sprayed bythe brush drains back intothe well 4, and may be recirculated unt-il such time as it is thoughtnecessary for a cleansing of the articles, after which a new supply ofclear water may be used for rinsing purposes.

It will be noted that simplicity of structure is obtained and thenumberl of moving parts minimized by utilizing the motor shaft both forrotating the brush and for operating the impeller, which is a salientfeature of the invention. It is intended that' the Water be thrown in aradial direction with considerable force by the rapidly rotating brushso as to efectively remove all foreign matter from the articles to beWashed by such action which does not too firmly adhere thereto. Due tothe brush being disposed centrally of the receptacle and the provisionof conslderable space between the brush and the article' holdingfingers, such articles on which foodstuffs have been allowed to dry andto firmly adhere thereto, may beimanually and handily brought inbrushing contact with the rotating brush to remove such matter heforeplacement on the supporting lingers, when the normal operation of theWasher will complete the cleansing operation. From the foregoing it willbe seen that a dish washing machine is provided which is simple inConstruction, involving a minimum of moving parts, and with which dishesand cutlery can be rapidly and thoroughly cleansed.

What is claimed is l. A dish washing machine comprising a receptacle,means for supporting dishes therein, a high speed motor having a shaftextending vertically in said receptacle, a brush, connected to saidshaft within said receptacle, and means for discharging liquid on saidbrush, said motor rotating said brush at high speed'whereby the liquiddischarged on the brush is thrown outwardly to cause a spray.

2. A dish washing machine comprising a receptacle, means for supportingdishes therein, a brush rotatably mounted in said receptacle, means fordischarging liquid on said brush, and means for rotating said brush athigh speed whereby liquid discharged on said brush is outwardly throwntherefrom by centrifugal force to form a spray.

In testimony whereof I aiiix my signature.
